The results showed:(1) the cellule morphous and the disposition in chick embryo of PGCs were coincident no matter stained by PAS or HE staining, and HE staining could disclose the morphologic characteristics more clearly, exactly and completely;(2) genesis of blood island could be observed at the boundary of light and dark region of the extraembryonic blastoderm at about 26 hours;(3) both the blood vessel endothelium cells and free cells of the blood island were differentiated from PGCs. The generating of genuine yolk sac was at about 44-48 hours.

结果表明：①用经典的识别原生殖细胞的PAS染色方法与HE染色所观察到的PGC在鸡胚的分布及细胞形态基本一致，而HE染色较PAS法能更有助于清晰、完整、准确地识别PGC的细胞内部结构特征；②在孵化26小时的鸡胚胚外胚盘的明暗交界处可见血岛的发生，血岛发生的时间比真正的卵黄囊产生时间（大约44-48小时）要早很多；③血岛周围的血管内皮细胞与管腔中游离细胞都来自PGC。

Therefore, if a region has a simple shape of the same architectural style and function-defined border, in a unique urban environment, a clear link with the surrounding region, visually prominent. So there's no doubt in the region.

所以，一个区域如果具有简单的形状，一致的建筑式样和功能，明确的边界，并且在城市环境中独一无二，与周围区域连接清晰，在视觉上突出，那么这个区域的存在一定不容置疑。

On Earth, breccia is a jumble of broken rocks cemented together by fine-grained material that is found around volcanoes and impact craters.

在地球上，角砾岩是火山周围和遍布陨石坑中由破碎岩石胶混合粘结在一起的细粒物质。

60Mm anterior and 1. 20mm lateral to bregma and 4. 00mm ventral to the cortical surface . 2 days later, ICH was induced by the standard method. At 7d, animals were sacrificed to investigate distribution of EGFP-expressing or BrdU-labeled cells around hemotoma.

根据以上实验结果，在分离、培养、传代获得NSC的基础上，采用pEGFP转染或BrdU标记体外培养NSC后，将细胞移植入前囟前1.60mm，矢状缝向右1.20mm，深4.00mm的细胞增生活跃的前脑脑室下区。2d后诱导脑出血模型，出血后7d处死动物检测EGFP或BrdU阳性细胞在血肿周围的分布情况。

Society is improving by the minute, and the environment is constantly changing.

殊不知，社会每时每刻都在前进，周围的环境在不断变化！

Classical heaviness and an old book store in a certain bystreet within Paris where a familiar relics of poems are read our longing for the nature positioned in memories of our past is expressed in peace and freedom just like stop of flows of times.materials of motif introduced from the nature,which are felt more comfortable under warm sunrays in afternoon,are similar to unique sturdiness and shapelessness and provide convenience together with neutral colors.

在巴黎街道一个有着拿破仑时期典型装饰的老书店里面自在而平静的读着熟悉而久远的诗歌，它勾起了我们记忆深处对大自然的渴望，如同淅淅沥沥流过的时间之水。周围那些以大自然为主题的建筑物在午后温暖的阳光下显得更加生动，虽然他们笨拙而造型感不强烈，却为人们提供了方便和良好的视觉享受。

RESULTS: The carbon femoral head prostheses implanted in animals produced non-toxic side effects, without significant inflammatory response or foreign body reaction. Furthermore, new cartilage tissue around carbon prosthesis was found, while there was no obvious wear debris after sports experiments.

结果：碳质股骨头假体在动物体内无毒副作用，无明显炎症反应和异物反应，在碳质假体周围发现有新生软骨组织，运动实验后碳质股骨头表面没有明显磨损和碳颗粒游离现象。

If you can not find the angels around you, just try to be an angel. To help the people around you. Be more patient, be more understanding, be more carful about others, be more kind......Even you are not beautiful, just to have a more beautiful heart. And to be an angel will be more happy then you find an angel.

如果你在你身边没有发现天使的存在，那你就试着让自己成为一个天使，去帮助你周围的人，多一点耐心，多一份理解，多一点关怀，多一份善良，哪怕你不是那么漂亮，但是拥有一颗善良的心，你就是那天使，你也将拥有更多的快乐，你也将会发现原来天使就在你身边。

Learn to carve your gratitude in stone, then you know how to care about other people around you .

学着将你的伤痛写在沙地上，这样你就会忘记仇恨；学着将你的感激刻在石头上，这样你就会懂得如何去关心你周围的人。

The strange silence, broken only by the measured dip of the oar and the soft plashing of the water against your cleaving prow, and the occasional hoarse cries of the gondoliers as you pass another of these black, funeral barges; the few and feeble lamps, giving you momentary glimpses of balconies and finely carven arches; the sudden intensification of the silence and the darkness as you abruptly leave the Grand Canal and slip along one of the narrower waterways, always with tall houses on both sides of you, and above you a clear sky of stars, stars reflected tremblingly on the black waters----thousands of tourists must have tried to describe all this, but the magic and the mystery and the beauty of it defy human speech.

此情此景，若非失忆，你怎能忘记。四周静得出奇，只听见船桨嘎吱嘎吱的轻吟，溅起的水花在船头轻唱；不时有黑色船只经过，又闻船夫沙哑的寒暄声。岸上的路灯依稀可见，寥寥无几，却也能让你匆匆瞥见建筑的阳台，和那精雕细刻的拱门。小船从大运河突然飘向窄水道，夜色更深，周围更静。左右高楼时现，仰望夜空，繁星点点，清晰可见，倒映在暗淡水面的星星，随波起舞。不知多少文人墨客皆欲描绘此景，但却苦于辞藻有限，世俗的语言无法将它的迷幻之美一一描绘。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
